These CMOS products are designed to drive liquid crystal displays by converting 5 volt serial data to parallel segment and backplane waveforms with amplitudes up to 30 volts. The HI-8020 & HI-8120 differ from the HI-8010 by only the shift register clock and chip select gating logic. The HI-8020 has TTL logic inputs whereas the HI-8120 has CMOS logic inputs. Both devices can drive up to 38 segments and have 3 possible shift register data taps to provide options to cascade devices for larger displays. Data is clocked into a 38 stage shift register and parallel latched before the output translators by a Load input. The HI-8020 & HI-8120 are available in ceramic leadless chip carriers and plastic PLCC packages.

A Logic "1" present at the Load (LD) input will cause a parallel transfer of data from the shift register to the data latch. If the Load (LD) input is held high while data is clocked into the shift register, the latch will be transparent. All four logic inputs are TTL compatible on the HI-8020 and CMOS compatible on the HI-8120. To display segments, a Logic "1" is stored in the appropriate shift register bit position, and the segment output is out-ofphase with the backplane. The backplane output functions in 1 of 2 modes; externally driven or self-oscillating. When the LCDØ input is externally driven with the LCDØOPT input open circuit (Figure 2), the backplane output will be in-phase with LCDØ. Utilizing the self-oscillating mode, inputs LCDØ and LCDØOPT are tied together and connected to an RC circuit (Figure 3). A 150KW resistor with a 470pF capacitor generates an approximate backplane frequency of 100Hz. The LCDØ/LCDØOPT oscillator frequency is divided by 256 to determine the backplane output frequency. The resistor value (R) must be at least 30KW for proper self-oscillator operation. For displays having a number of segments greater than 38, two or more of the display drivers may be cascaded together by connecting the serial data output (DOUT) from the first driver, to the serial data input (DIN) of the following driver, etc.(See Figures 2 & 3). Data out (DOUT) will change state C R on the rising edge of the Clock (CL). Clock (CL), Load (LD) and Chip Select (CS) should be tied in common with each other, respectively, between all cascaded display drivers.
